Black screen OBS

[Blackckk]

hello ... i have a problem and i can't solve this problem. :(( I need help.

I have been using OBS Studio for two years and I am satisfied with it. But I don't know why, but I have a black screen. In the camera settings, but I can see the screen. Does anyone know the solution to my problem, please?

Click the source in the Sources list, then press CTRL+R, then CTRL+F. This will reset the transform, then fit it to the screen.
Sometimes when a source is created, for some reason it's WAY outside of the canvas area, or scaled down tiny. You can also right-click the source in the Sources list, go to Transforms, then choose Reset Transform, then go there again and Fit To Screen to do the same thing, if the hotkeys don't work for some reason.
